“…During recent years, there has been a growing interest in its application [29,30], e.g., as redox-active ligand [31], in electronics [32], non-linear optics [33], catalysis [34], molecular recognition [35], and in the synergism of antitumoral activity [36]. However, by no means, all of the ferrocene derivatives have good solubility, making it difficult to study their redox properties that are fundamentally important for practical applications.…”

A new carbon paste electrode is described, which contains the room temperature ionic liquid (RTIL) tri(tertbutyl)(dodecyl)phosphonium tetrafluoroborate as binder. The advantages of this electrode are a high conductivity, very wide electrochemical window (5.6 V from 2.7 to −2.9 V, one of the widest ever reported for RTILs), stability in time, and reproducibility. This RTIL-carbon paste electrode (CPE) allows determining the current-voltage characteristics of redoxactive compounds. Thus, the newly synthesized insoluble compound poly-tris(μ 2 -1,1′-ferrocenediylphenylhydrophosphinato-phenylphosphinato)-iron(III) tetrahydrofuran solvate {μ 2 -[Fe II (η 5 -C 5 H 4 -P(PhOO)(η 5 -C 5 H 4 -P(PhOOH))] 3 Fe III }·THF was studied, and a quasi-reversible three-electron oxidation could be observed at a potential more positive than that of ferrocene. A comparison of voltammograms on the paraffin-CPE and on the novel RTIL-CPE shows the advantages of the latter.

DFT B3LYP/LANL2DZ method was employed to calculate electron properties and the second-order nonlinear optical (NLO) respond of platinum (II) complexes which have been synthesized by Weinstein group. 4,7-diphenyl-1,10-phenanthroline shows the ability to push electron in these complexes. Metal Pt plays a balancing charge role. Comparing complex 1b-6b with complex a, the β vec value of complex 1b-5b is larger than one of complex a, while the β vec value of complex 6b is smaller than one of complex a. In these seven complexes, the β vec values of complexes increase with decreasing of the energy difference between HOMO and LUMO. Moreover, the electron transfers from deeper layer occupied orbitals to empty orbitals have a distinct contribution to second-order NLO coefficient.Pt (II) complex, DFT, chromophore, second-order NLO property

“…The design and syntheses of functional complexes, constructed from multi-ferrocene ligands and transition metals, have attracted much interest because of their potential applications as electron reservoirs [1,2] , sensitive electrochemical probes [3,4] , ionic liquids [5][6][7] , nonlinear optical materials [8,9] , catalysts [10] and building blocks for molecular electronic devices [11][12][13][14][15] . The redox between the ferrocene (Fe(II)) and ferrocenium (Fe(III)), with fast and reversible electron transfer, is one of the important properties of ferrocene derivatives.…”

Two new metal-centered ferrocene complexes Ni(SCN) 2 (L) 4 (1) and Cu(OAc) 2 (L) 2 (2) (L = 1-[1-ferrocenylmethyl]imidazole) have been synthesized and characterized by elemental analysis, single crystal X-ray diffraction analysis, spectroscopic and cyclic voltammetric measurements. The geometry of Ni(II) in 1 is octahedral, with four ligands in the equatorial plan and two thiocyanate anions at the axial site, while that of Cu(II) in 2 is a distorted octahedron formed by two chealted OAc − and two ligands. Single crystal X-ray diffraction studies reveal that there is partial electron delocalization from ferrocene to imidazole in the two complexes. Electrochemical measurements exhibit that complexes 1 and 2 undergo similar reversible one electron redox processes, suggesting that the ferrocene moieties are equivalent and there are no interactions among them.ferrocene, imidazole, complex, crystal structure, electrochemistry
